The present invention relates to table sewin machines of the type inwhich a desk-like or similar support for the machine is provided in itstop with a well or recess into which the machine can be lowered when notrequired for use. The main object of the invention is to provide meanswhereby the treadle is automatically folded away, or brought into theoperative position and positively connected to the driving means, whenthe machine is folded away, or brought into operative position,respectively.

A further object of this invention is to enable the leg space of thetable which contains the treadle to be left unencumbered by the treadlewhen the machine is folded away so as to provide a neat and tidydesk-like table when the machine is not in use, and with none of theoperating mechanism visible.

Referring to Figs. 1 to '7 of the drawings the head of the sewingmachine table is indicated by the reference numeral I and is providedwith two 5 drawers, the sewing machine 2 being swung into the concealedposition in the head i. Within the head is provided means for supportingthe sewing machine 2 so that it can be swung down from the positionillustrated in Fig. 2 and Fig. 5 to the position below the top surfaceof the head I, as shown in Figs. 1, 3 and 4. The rear edge of the baseplate I of the sewing machine is connected by means of hinges to thehead I, and the front edge of the sewing machine base i rests on aprojection on a movable flap when the machine is in use. When the sewingmachine is to be folded down below the table top so as to depend fromits said hinges, the flap 35 is first swung upwards in known manner, sothat its projection clears the front edge of the base plate ,1, and thesewing machine is then lowered within the head I. In this position therecess of the head concealing the machine 2 may be covered by a panel36. An arcuate plate 6 is pivoted at its ends link fashion to coiledtension spring 26 and to a part of the head i to act as means forlimiting the downward swing of the machine to the angle which brings thebase plate I to the vertical depending plane as shown in Figs. 4 and 4A.The springs raise the arcuate plate 6 when the machine 2 is raised tothe operative position. A treadle 4 for operating the sewing machine islocated near the floor between the two box-like side members Ia and isconnected at one end by two hinges 23 to an oscillating plate 19 (Figs.3B and 6), so that it can be swung to the vertical plane position shownin Figs. 1, 3 and 4 closing the inner side wall of the left hand(looking at Figs. 2 and 3) box-like part la. The oscillatable plate issupported by a foot bearing 2| comprising two supports 21a and onemember 2113 mounted between the supports to oscillate about the axis21-0 (Fig. 3B). The oscillatable plate I9 is fixed to the member 2 lband is thus oscillatable lengthwise of the treadle 4. When the treadleis folded upwards the foot bearing 2| is concealed.

In the other box-like side member la is. accommodated a driving wheel 3,the bearing 3a of which is fixed to the outer wall of the appropriateside member la. The usual connecting rod 5 connects the wheel 3 to anoscillatable plate 20 similar to the plate 19 and supported on a footbearing 22 comprising two supports 22a, one oscillatable member 22b andan axis 220 (Fig. 3G) in similarity with the bearing 2i. The customarybelt 3b passes around the driving wheel 3 and a pulley 2a of themachine.

The treadle 4 is automatically swung to the folded and operativepositions contemporaneously with the corresponding adjustments of thesewing machine. For this purpose, attached to the side edge of the baseplate i which is the lower when the machine is folded, is one end of anangle iron 8 (see Figs. 3, 3A and 4). The other end of the angle iron 8is fixed to a. shaft 9 supported just below the table top by twobearings l E] and to this shaft ii is fixed one end of an arm i l theother free end of which carries a roller or pulley 12 which bears uponthe horizontal upper central part [30. of an inverted U-shaped member i3slidable in lugs it fixed to the inner wall of the appropriate box likemember la. Coiled tension springs 21 tend to raise the U-shaped member13. The lower ends of this member it are pivotally connected to a pairof links 65 (see Fig. 3) which are cranked towards each other as at Hiato bear against a pair of arcuate bars i8 (shown in Figs. 3 and 3B andin broken lines in Fig. 6) when the machine is folded away. These linksH are formed with wedge-like projections H, and the inner wall of theappropriate box-like member la is likewise formed with an oppositelydirected pair of wedgelike projections is, or there may be a single widewedge-like projection. These opposed wedge-like projections i6 and i?direct the links l5 downwards and outwards when the U-shaped member i3is pushed downwards against the influence of the springs 21. The arcuatebars l8 are fixed to the treadle 6 and act as arms receiving thedownward pressure of the links IE to raise the treadle 4 to the foldedvertical position.

When it is desired to fold away the sewingmachine, the machine is firstlifted a little upwards at the front edge of the base plate 5 resultingin the flap 35 also being turned upwards, whereupon the sewing machine 2is lowered into the head I. The base plate 7 of the sewing machine isnow turning on its hinges and at the same time swinging the arcuateplate 6 downward, resulting in the angle iron 8 rotating the shaft 9,whereby the member I i is subjected to turning. The pulley l2 on themember I i now presses down the U-shaped member 53, and the links l5,whereby the lower end parts of the levers I5 are pressing on the arcuatebars i8, which latter swing the treadle to the vertical position. Whenthe sewing machine 2 is swung up to the operative position an oppositeswinging of the treadle 4 from the vertical to the horizontal positionautomatically takes place. By this means there are no obstructive partsbeneath the head or table I, and also the machine is obsoured by a flap36 neatly filling the opening through which the machine swings. Amovable panel 24 obscures the driving wheel and associated mechanismwhen the machine is not in use, this panel 24 being slidable in avertical plane. The upper end of this panel 24 is connected by a pair ofcoiled tension springs 25 to the head I and to the flap 35 respectively.These springs tend to raise the panel 24 but a limit to the raisingmovement is set by the lower surface of the plate 6 which engages theupper edge of the panel 24 (compare Figs. 4 and 5). It is seentherefore, that in the position according to Fig. 4 the panel 2 3 willbe pressed downwards to close one side member ia, but in the positionaccording to Fig. 5 the springs 25 may act to maintain the panel in araised position, making the mechanism available. Secured to the flap 35is the upper end of a rope 34 the lower end of which is carried under afixed guide pulley 33 and ultimately secured to an eye 28b of a U-shapedmember 28, the extremities of which are shaped as forks 28a adapted toembrace the appropriate end of the treadle 4 when the treadle is in theoperative position as shown in Figs. 5, 6 and '7. The fork 28 is guidedfor horizontal sliding movement by a pin 32 and slot 3| and twolongitudinal channels 39 in the oscillatable plate 26. The U-shapedmember 28 is urged outwards against the appropriate edge of the treadle4 by means of a spring 29, shown in Figs. 3C, 5, 7 and 7A. The ends ofthis spring are fixed to pins 26a, 201) at the plate 23 and the centralportion of the spring engages the eye 28b of the member 28. The U-shaped member 28 is adapted to hold the treadle 4 in horizontalposition at its free end in firm connection to the oscillatable plate26. The U-shaped member 28 is thus automatically engaged with the freeedge of the treadle 4, so that, when the sewing machine is turnedupwards, the flap must first be raised, whereby a pull on the rope 34takes place, thereby drawing the U-shaped member 2d into the drawercase, thus enabling the free end of the treadle 4 to be lowered into thehorizontal position without engaging the forks 28a. When the sewingmachine reaches the raised position, the fiap 35 is lowered, whereby thetension on the rope 34 is released and the forks 28a pushed by thesprings 29 into locking engagement with the treadle. When lowering thesewing machine below the table top the reverse operation takes place, i.e., at first the forks 23a disengage with the appropriate edge of thetreadle thus enabling the automatic raising of the treadle andsubsequently the U-shaped member 28 is moved to its outermost positionby the springs 29.

In the modification illustrated in Figs. 8, 9, and 11 the spring leadedU-shaped member i3 is guided between bars 3?. The lower end of theU-shaped member i3 is connected to one end of a pair of links 38, theother ends of which links are formed with square holes 39 adapted toreceive square ended pins ii! on a transverse shaft ii on the treadle 4.The links 38 are connected by bosses at their apertur d parts 39 to thelower end of a pair of arms "23 pivoted at their upper ends to lugs 42fixed to the member a, and the lower ends of these arms .3 are aperturedto slide upon the ends of a horizontal tube .45 supported at its ends inbearings 44. Coiled compression springs 4'! are interposed between thearms 43 and abutments 46 on the tube 45.

The limbs of the U-shaped member 53 are resilient to enable them to bemoved towards each other by reason of the tension applied to the rope 34which is anchored at one end to a screw 50 threaded into one of the arms43 within the tube 45 and passed over a pulley is secured within thelower end of the other arm 43. The screw 50 and the pulley 48 slide inslots 4% in the tube 45. A pair of opposed fixed angle bars 5! serve asabutments against which the lower ends of the U- shaped member it arepressed when in their lowest position in order to maintain engagement ofthe square pins 48 and the square holes 39. The end of the treadleremote from the oscillatable plate is formed with a pivot 52 detachablyengaged in lug 5.5.

When the rope 34 is drawn upwards by the flap 35, the rope draws thelinks 38 towards each other whereby the end pins 49 on the shaft iiienter the holes 35 and when the base plate 1 forces down the fork l3when the machine is lowered, the links 38 swing the treadle 4 upwardsinto the vertical plane as shown in broken lines in Fig. 8. When thebase plate I is swung upwards to the operative position, the U-shapedmember I3 is drawn upwards by means of the springs 21 whereby the links33 assume their upper position as shown with the full lines in Fig. 8,so that the links 38 are disengaged from the abutments 5i and thesprings 47 press the links 38 apart, disengaging them from the pins 49,thus releasing the treadle into the operating position.
